YAPP: A Sailing Raspberry Pi

Yes you can, but DVI doesn't carry sound, so you'll have no way of hearing the sound on videos as there's no audio output on the Pi

I'm sure I've seen an adaptor which converted HDMI to DVI + audio on a separate connector. Not particularly cheap though as it presumably has to decode digital audio from the HDMI.

Hmmph.

Though the benefit of the VIA APC is, I guess, that (a) Via is a huge company, and (b) it has a VGA output so putting a battery powered display in a boat would be a chuff-load easier...
 
So, where's everybody gone? :rolleyes:

Arrived back from holiday to find a Pi waiting for me :)

All up and running with "Squeeze" while SWMBO was unpacking :o

I thought I'd try an old Logitech wireless keyboard/mouse combi to save a USB port, it works first time (unlike trying to install it under Windows which is a real PITA)

I thought this might be a useful tip for those trying to minimise the sprawl of wires aboard. :)

Lucky git,

Still waiting on mine :(

I've made a social group for the raspberry pi and started adding some potentially useful hardware on to it for your interest

Just waiting for some decent weather so I can try it out afloat :(

I've built fldigi for wefax and Navtex, but as I can't get a clean SSB signal at home the results aren't very pretty.

OpenCPN is nearly there, but I'm still trying to get it working with AIS (using discriminator output from an old VHF)

It all seems so slow though, 100% CPU for both apps.
Compiling on the Pi is also slow and I haven't cracked cross-compiling yet.

Audio input £1.69 using one of these:

IWith regards to running performance, I have to say it's pretty slow, though seems to fit fine in the limited memory of the Pi. To give some idea of the speed, on zooming, redraws can take anywhere between a couple and ~10+ seconds, which, for me at least, is probably a little too frustrating to be usable.

out of interest, were you using hard float? i imagine that will make a large difference on something doing quite a lot of fp calculations....

Excellent question. To be perfectly honest, I don't remember, and I don't have the pi around any more. I wasn't cross compiling though, so I believe (very possibly erroneously) that the compile will have depended on whatever kernel/filesystem is/was on the default Raspberry Pi Debian distro....
 
OpenCPN successfully built under Raspbian ... a considerable improvement in performance, looks like it's fast enough to be usable.
